' GOLF-AND LIKE BALL.

To all whom 'it may concern: v

Be it. known that` I, ELLIS MILLER, a citizen of the United/States ofAmerica, and resident of 167 Oxford street, LondomW.,

England, have invented a certain new and useful Improvement i'n Golf andlike Balls, u

. applied is of the hollow-core type, the radioof which the following isa specification.

My invention will be better understood by referring to the accompanyingdrawings in which Figure 1 represents a diametral section through aball, according to my invention, having a core of mixed inert-and radioactive materiahsurrounded by an external envelop of rubber ror likeelastic material; Fig. 2l represents a similar section'in which theradio active material is centrally located and surrounded .by an envelopof inert material which is itself surrounded byV an envelop of rubber orlike elasticl material;A

Fig. 3 represents a similar section having a hllow central core of mixedinert and radio.

active material surrounded by an envelop of inert material, the wholelbeing covered by a jacket of rubber or like elastic material; and Fig.4: represents a similar section of a solid ball of rubber or likeelastic material having particlesof radio active mate' rial uniformlydistributed .throughout its.

mass.

In the several figures thefradio active material is designated by 1,the. elastic material by 2, the inert material by 3, the mixed inertarid radio active material 'by 4, andthe elasf Atic material withuniformly distributed radio active material therein' by 5.

This invention, relates to balls Eused in playing games, such as golffor example,

and composed of rubber, gutta percha, o r` other like material orcomposition either alone or in admixture, the'object of the inventionbeing to provide a'ball which shall be capableOf\performing, with agiven ex# penditure of energy on thepart of. a player v using the ball,a .longer flight thanthatfper'- mensions as at'present manufactured.

formed by balls of similar weight and di- According to thep esentinventonthere is provided within the improved ball, either separately,or in a state Of incorporation with the material or with one or'more ofthe materialswhereof the ball is made,A a

Application le March 2, 1916. Serial No. 81,677 K "radio-activesubstance o'r mixture such for example asa uranium mineral or orel ('e.g.,

pitchbl'ende) or the intensely radio-active bodies known as radium,polonium,- actinflum, mesothorlum,- and the like.`

When the ball towhich Vthe invention is active substance or mixture, ifpossessed of a high degree of radiant energyis located withinthe cavityin the interiOr 0f the ball,

substance or mixture and consequent detriment to the flight of the ball;whereas, if the radioactive substance or mixture be possessed of 'a lowdegree of radiant energy,l or is present as an ingredient in a materialof low radioactive power2 said material may itself lill the cavit withinthe ball so that the employment o an Jinert lling medium is in such casenot lnecessary.

-Whether the bali] be Of the solid or hollowcore type, thev.radio-'active substance or mixture may be-incorporatedin the Inaterialof which the ball as a wholeis formed, or in one. or more of the layerswhereof the tain a composition of perfect homogeneity so as to'insureequal radio-activity in alldirections irelatively to the center of the,

ball.

The radio-active substance or mixture employed may be used alone or incombination with any of the filling agents commonly used in themanufacture of ballssuch as golfballs for example. f
